The particles can slide past one another. This is because they are far apart.

What are characteristis of a good conductor?
It is when an object is transferring energy through the object easiily
What are the different types of heat transfer?
There are three types of heat transfer, namely conduction, convection and radiation. Heat is transferred until the reach a state of equilibrium. Conduction is basically the transfer of heat through a surface of contact, such as a fire to the base of a pot. We say that a material is a good or poor conductor of heat when heat travels quickly or slowly in that particular material. Good conductors of heat are metals whereas poor conductors of heat are rubber and Styrofoam. Conduction cannot occur in a vacuum. Convection is the transfer of heat through molecules. It can only occur in liquids and gases as there are relatively big spaces between the molecules. A convection current is where hot air rises and cold air sinks. Convection cannot occur in a vacuum. Radiation is the transfer of heat through a vacuum. Heat is transferred from the Sun to Earth through radiation.
What is a good sentence with the word 'convection' in it?
Convection is only one of the three types of heat.Can't we use the convection oven?
Is empty space a good insulator and why?
Yes,empty space is a good insulator because heat cannot move through empty space by conduction or convection.
Do objects need to be touching to transfer charge?
No. A charged raincloud does a pretty good job of transferring its charge to the ground, through the phenomenon we call "lightning".
Why water is a good conductor of heat?
Water is a good conductor of heat because it is a liquid thus convection currents can flow as well as transferring heat by conduction through the water molecules.

Yes,empty space is a good insulator because heat cannot move through empty space by conduction or convection.
What is a good sentence for convection?
Convection is the movement of matter due to differences in density.
What is convection in a fan assisted oven known as?
convection is transfer of heat from a hot section to a cold section through certain types of mediums, such as solids air liquid; good conductors.. by aka femi-akoms

Are gases thermal insulators?
Yes. Gases have low thermal conductivity, so if you keep convection low (bulk movement of the gas) they are good thermal insulators. Refractive bricks used in kilns (high temperature ovens) made of silica and some other low conductivity materials are made intentionally porous.
How is the aluminum bar transferring heat?
its a good conductor of heat
Thermal conductors are substances that do what?
They are good and conducting and transferring heat.
Are liquids and gases good insulators?
Gases are good insulators because most insulating materials which have gas filled pockets which means gases are good insulaters. Hope this helps :)
